System API execution is not effective, you can check if it is related to 360 security guards?!

Today is writing a tool software that uses a system API: mouse_event()

The code is as follows:

Mouse_event (Mouseeventf_absolute | Mouseeventf_move, x2, y2, 0, 0); Move to the specified position

But I found a problem, when the software window is active, mouse_event can execute normally.

When the software window is minimized, Mouse_event has no effect.

For this problem, I spent nearly 3 hours, also did not check out the problem where?

Finally try to put 360 security Butler quit, run the program again, Mouse_event () unexpectedly everything is back to normal.

I started the 360 again, try again, mouse_event () again.

Final conclusion:

360 for security reasons, Mouse_event () is masked by 360 when the program window is inactive.

If 360 can be shielded mouse_event, give a safety hint, just fine, so I don't waste so much time.

System API execution is not effective, you can check if it is related to 360 security guards?!
